How Long Does CBD Stay In Your System?

Jun 4, 2020

Typically, CBD stays in your system for between 2 to 5 days. However, this is only an estimate and it may differ for some people, potentially staying in their system for a matter of weeks.

This post will explore the contributing factors which determine how long CBD stays in your system, enabling you to get a more accurate understanding of how long it might stay in your system for. But first, let’s take a quick recap of what CBD is.

What Is CBD?

CBD, which is short for cannabidiol, is a naturally occurring compound from the cannabis plant. Ulike THC, which is the psychoactive substance in marijuana, CBD does not produce a high. CBD contains very little trace of THC as it is derived from the Hemp plant. In the UK, CBD products are legal as long as they contain less than 0.2% THC.

Many people are put off from using CBD due to its association to cannabis and the stigma behind it, however the number of users is fast growing and the health benefits are clear to see. Notably, CBD is commonly used to address anxiety, insomnia and chronic pain. Many tests and studies have been carried out, although the full extent to CBD effectiveness is not fully understood by scientists

Will CBD Show Up On A Drug’s Test?

The reason many people wonder how long CBD stays in their system is because they may face drug tests as part of their job or other commitments. We’ve written a whole blog covering if CBD will show up on a drugs test, however we’ll cover a brief explanation here.

It is extremely unlikely that CBD will result in a positive drugs test, although not impossible. Drugs tests will look for the presence of THC in the body, and given that CBD products are legally only allowed to contain 0.2% THC, you would need to consume a very large amount of CBD oil in order to test positive (roughly you would need at least 1000 milligrams in a single day).

For those that are still hesitant about the possibility of testing positive on a drugs test, many CBD products are available which contain 0% THC. You should look for a broad spectrum CBD oil or CBD isolate product, as both these types of products contain 0% CBD. Be sure to check out the lab report to double check that the products contain 0% THC too.

At The CBD Planet UK, we have a range of products which contain 0% THC, as well as CBD isolates. All of our products have a lab report so you can get peace of mind on the amount of THC each product contains.

Factors Affecting How Long CBD Stays In Your System

There are a number of factors which determine how long CBD stays in your system. 

How Much CBD You’ve Taken

How much CBD you’ve taken is one factor which contributes to how long it stays in your system. Like with any substance, the more CBD you’ve taken the longer it will take to get out of your system. Your liver is only able to filter so much out of your system at once.

Your Body

Everyone’s bodies are different and there are a number of ways this can impact how long CBD stays in your system. Your metabolism is one of the main ways, as it affects how long it takes your body to excrete the CBD from your system. However other factors that also contribute are your BMI (body mass index), as well as your water content. 


What foods you eat, how much you eat, and when you eat all play a role in determining how long CBD stays in your system. Certain types of food can enhance bioavailability and increase the concentration of CBD in your body. Taking CBD on an empty stomach can increase the speed at which it goes through your system, as the CBD gets metabolised quicker.

How Often You Use CBD

If you use CBD frequently then this will increase the length of time that it stays within your system. CBD builds up over time when it is used regularly, and so those who only use it occasionally will clear it from their system much faster.

How You Take Your CBD

The way in which you consume your dose of CBD plays an important part in determining how long it will stay in your system. If a method of consuming CBD allows you to feel the effects sooner, then this also means that the CBD will leave your system sooner.We’ll discuss some of the most common methods for taking CBD and what they mean for the amount of time CBD stays in your system.

Sublingual Oils

When you take CBD sublingually, meaning you take it by placing a few drops of CBD oil underneath your tongue, the CBD is absorbed into your bloodstream through the mucous membranes within your mouth which bypasses the digestive system. This means it gets into your system faster than edibles but also means it stays within your system for longer.

Edibles & Drinks

With CBD edibles and CBD drinks, the CBD stays in your system for longer than oils. The CBD is swallowed which means it doesn’t enter the bloodstream straight away and is first digested before going on to the liver and entering the bloodstream from there. This process means it takes longer for CBD to have an effect, and also takes longer for it to leave your system.

Creams & Topicals

CBD creams and topicals are applied directly to the skin. The CBD is absorbed directly through the surface of the skin and then interacts with cannabinoid receptors without entering your bloodstream. CBD creams are good for administering CBD to a certain problem area without the whole body effect, however they offer one of the slowest ways for CBD to get into and out of your system. 


Vaping CBD is one of the most common ways of taking CBD. When you vape CBD, perhaps using a CBD vape pen or CBD vape juice, the CBD enters your lungs and goes directly into your bloodstream. This means it takes effect almost immediately and is also able to leave the body quickly.

Concluding Thoughts

You should now understand the many contributing factors which determine how long CBD stays in your system. Our bodies differ, our usage habits differ, and the way we take our CBD can vary. CBD is unlikely to stay in your body for longer than 5 days, however this is not always true and it is possible that it could remain in your system for a matter of weeks. If the reason you are concerned about having CBD in your system is to pass a drugs test, then we would recommend using CBD products which contain 0% THC to mitigate the risk of testing positive.
